LETTER-PRESS.

SPECIFICATION forming part of Letters Patent No. 347,536, dated August17, 1886.

Application filed April 29,' use.

To all whom it may concern.-

Be it known that we, ANsELM VEILLEUX and WALTER BENINGTON, citizens ofthe United States, residing at Stillwater, in the county of Washingtonand State of Minnesota, haveinvented certain new and useful Improvementsin Letter-Presses; and we do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

Our invention relates to letter-presses. It pertains particularly to themeans for feeding the movable plate, whereby the same may be readily andquickly moved and be positively held when adjusted to an operativeposition.

It consists in the novel features more particularly hereinafter setforth and claimed, and shown in the annexed drawings, in which Figure 1is a perspective view, with parts broken away, of a press of ourconstruction provided with our improvements. Fig. 2 is a section on theline 00 a: of Fig. 1. Fig 3 is a perspective detail view, on an enlargedscale, of a pawl for operating the stem of the movable plate. Fig. 4 isa perspective detail view of the spring for returning theoperating-lever to a normal position.

The base or bed A of the press is provided with an overhanging arm, B,having a vertically-apertured head, B, through which a rod or stem, 0,carrying the movable plate D, works. The lower portion of this stem orrod is provided with ratchet-teeth c 0, preferably on two sides. Aretaining-pawl, E, pivoted to one side of the head B,has one endprovided with a tooth or teeth, 6, which project through the side of thehead and engage the teeth on one side of the bar, so as to hold theplate against vertical displacement till the pawl shall have beendisengaged from the bar. A lever, F, pivoted at its inner end to a sideof the head having a seat, f, on its under side, near its fulcrum, hasone end of a pawl, G, seated therein and secured in place by arulejoint. The other end of the pawl is bent to one side to engage theremaining ratcheted side 0'. Spring H presses the free or bent endSerial No. 200,301. (No model.)

9 of the pawl close to the bar. Lugs g, projecting laterally from thebent end of the pawl, engage and ride cams or inclines 1'), extendingfrom the lower portion of the tubular head,and disengage the bent end ofthe pawl from the teeth on the bar when the leveris at its highestpoint. Spring I, fastened to the head at one end and provided with slott at its other end, is connected with the lever F by a turn-button,f,working in the slot. The head of the turnbutton projecting on eachside of the slot engages the spring, which, exerting an upward force,elevates the lever when released after being depressed. By pressing onthe outer end of the pawl E it is disengaged from the stem of themovable plate, which latter is free to be moved into any desiredposition or elevation by raising or lowering the bar, which is free tobe moved within the head. The plate being adjusted, is held in suchposition by the pawl E, which, being released, is caused to engage thebar bya spring, e, forcing outward on its upper end. A further downwardadjustment may be had by pressing down on the outer end of the lever F,carrying with it the pawl G, which, riding down the incline, contactswith one of the teeth, 0, on the bar. During this adjustment the pawl Erides the teeth and engages the next higher. By this positive connectionthe plate is prevented from accidental vertical displacement, so commonin ordinary screw-presses. By pressing in on the outer end of the pawl Ethe plate may be elevated, either mechanically or by hand. In the formerinstance it maybe done by aspring, J, suitably interposed between theplate and arm. The arm B may be continued across and attached to theopposite side of the bed in the usual manner, in which case the pawl Ewould be on one side and the lever F on the opposite side. Suchconstruction would involve no departure from the spirit of ourinvention.

Having thus described our invention, what we claim, and desire to secureby Letters Patent is 1 A letter-press consisting of the followingelements in combination: a bed, an overhanging arm having a verticalaperture, a bar provided with teeth and movable through said aperture, aretaining-pawl,an operating-lever,

a pawl intermediate the lever and bar, and a plate carried by the bar,substantially as and for the purpose set forth.

2. The combination, with the bed and over- 5 hanging arm verticallyapertured, of a bar provided with teeth working through said aperture,an operating-lever, a retaining-pawl, a second pawl intermediate thelever and bar and contacting with the latter at each down to ward strokeof the lever only, a liftingspring connected with the lever, and a plateconnected with the lower end of the bar.

3. The combination of the bed, the overhanging arm vertically apertured,a ratchet- I 5 bar working through said aperture, a retaining-pawl, alever, a pawl pivotally conneetel with the lever and having lateralextensions,
